Glan Thompson Polarizers
Feature and advantage:
- Two Prisms Structure and Glued together.
- Medium polarization extinction ratio
- Wide Acceptance Angle
- Suitable for medium and low laser power
PRODUCT
Detail
The Glan Thomson prism is made of two Calcite prisms or two a-BBO prisms cemented together. The a-BBO polarizer can be used from 200 to 1100 nm, and the Calcite polarizer can be used from 350 to 2300 nm. It has a higher extinction ratio and a larger field angle. For example, the field angle of the a-BBO Glan Thomson polarizer is greater than 15 degrees.
